(This problem accounts for 45% of users who reported feedback）

Here are some troubleshooting steps you can take:

1. Check Compatibility:
   
   Ensure that the USB-C Hub is compatible with your device. Some hubs may have specific requirements or limitations regarding the devices they can support.
   
   

2. Secure Connection:
   
   Make sure that the USB-C Hub is securely connected to your device's USB-C port. If it's a detachable connection, reattach it to ensure a proper fit.

3. Power Supply:
   
   Some USB-C Hubs require external power, especially if they have multiple ports or are designed to support power-hungry devices. Check if your hub needs an external power source and ensure it is connected.

4. Update Drivers:
   
   Ensure that your device's operating system and drivers are up-to-date. Sometimes, a firmware or driver update may be necessary for proper functionality.

5. Try Another HDMI Cable:
   
   The issue might be with the HDMI cable itself. Test the hub with a different HDMI cable to see if the problem persists.

6. Monitor/TV Input:
   
   Confirm that the HDMI input on your monitor or TV is working correctly. Test the display with another device to rule out issues with the monitor or TV.

7. Check Display Settings:
   
   On your device, check the display settings to make sure it is configured to output to the HDMI port on the USB-C Hub. Some devices may require manual configuration.

8. Restart Devices:
   
   Sometimes, a simple restart of both your device and the USB-C Hub can resolve connectivity issues.

9. Contact Customer Support:
   
   If the problem persists after trying the above steps, it's advisable to contact the customer support of the USB-C Hub's manufacturer. They can provide specific guidance or offer a replacement if the product is defective.

By systematically going through these steps, you can identify and address the underlying cause of the display problems you're encountering with your USB-C Hub.

Customer case

Problem 1:

Flickering Monitors and Signal Loss After Firmware Installation on MOKIN Docking Station

Encountering issues with two connected monitors, where flickering occurs every 10-60 seconds (1 via HDMI, 1 via DP).

Following the UC0304F firmware installation instructions led to a no-signal situation on the display connected via the MOKIN docking station.

Additionally, using the provided tool, as per instructions, resulted in a complete halt of video connection via the MOKIN dongle, which previously worked but exhibited intermittent flickering.

This indicated a likely software/driver overlay problem rather than a hardware or cable issue.

Attempting the "wipe" option in the tool initially seemed successful, but subsequent attempts returned an "ISP mode failed" error with Error code 0x800.

Seeking clarification on this error and a resolution, suspecting a tool-induced change in the USB-C port driver.

Answer:
Incompatibility Prompt 0x800 and Diagnostic Recommendations

The 0x800 prompt suggests tool incompatibility with the computer, indicating no data erasure. Lenovo computers tested by technicians showed no issues.

For a more precise diagnosis, customers are urged to provide specific information:

product SN, details of loaded and running devices, hard disk brand and model, testing the feasibility of hard drive wiring replacement, and assessing if all hard drive interfaces connected to the product trigger disk disconnection.

The problem was successfully resolved by addressing the incompatibility prompt and seeking detailed diagnostic information from customers.

Problem 2:
SEDK0105 - HDMI Port Issues and Screen Flickering

Encountering issues with the HDMI ports on the SEDK0105. Initially, HDMI 1 port (60Hz) worked fine, but now it no longer functions.

HDMI 2 and HDMI 3 (both at 50Hz) are in use, but sporadically, the screen goes blank for 4-5 seconds, then resumes.

This occurrence, happening 2-5 times daily, lacks a discernible pattern.

Additionally, HDMI 1 is inaccessible, resulting in a black screen.

The Dell U3415W (3440x1440) monitor is connected via an HDMI to HDMI cable.

Steps to Address the Issue:

1. Use host1 for HDMI1:
   
   Ensure HDMI1 is connected using host1. Confirm the connection and check if the issue persists.

2. Test with Other Computers:
   
   For the flickering screen problem, conduct tests with other computers that support video output. This will help determine if the issue is specific to the SEDK0105 or if it extends to other devices.

3. Upgrade Computer System:
   
   Consider upgrading the computer system to the latest version. Compatibility issues and screen flickering may be addressed with an updated operating system.

By following these steps, you can identify whether the problem is related to the SEDK0105 itself, the monitor, or potentially the computer system.
